Running rawhide, targeted/enforcing.
After some problems completing daily updates, I decided to do a brute
force winnowing of the installed packages on my system via:
for i in `rpm -qa`
do
rpm -V $i
done
This generated lots of chaff, but I did get a few complaints and AVCs
from prelink. Here are a few examples:

I'm guessing this is probably an (obscure?) edge case, but is there a
missing transition from rpm_t to something like prelink_t?
Here is a particular case (this one generated the last AVC (execheap) above):
[root@localhost ~]# rpm -V compiz
prelink: /usr/bin/compiz.#prelink#.bdtGdC Could not trace symbol resolving
S.?..... /usr/bin/compiz
[root@localhost ~]# setenforce 0
[root@localhost ~]# rpm -V compiz
[root@localhost ~]#
